Embodiment Construction

[0010] Before any embodiment of the invention is explained in detail, it is to be understood that the invention is not limited in its application to the details of construction and arrangement of components set forth in the following description or shown in the drawings. The invention is capable of other embodiments and of being practiced or carried out in various ways.

[0011] The present invention includes methods and systems for creating maps by combining information from radar scans and optical image acquisitions. Survey vehicle 100 is maneuvered through the space, collecting one or more radar scans and optical images of the space. The space is any location where a detailed three-dimensional view of an area, such as a building in an urban environment, is desired.

[0012] In various embodiments, measurement vehicle 100 is a conventional vehicle, such as a car, truck, van, or motorcycle. In other embodiments, the measurement vehicle 100 is an autonomous or teleoperated v...

Abstract

A method of mapping a space using a combination of radar scanning and optical imaging. The method includes steps of providing a measurement vehicle having a radar system and an image acquisition system attached thereto; aligning a field of view of the radar system with a field of view of the image acquisition system; obtaining at least one radar scan of a space using the radar scanning system; obtaining at least one image of the space using the image acquisition system; and combining the at least one radar scan with the at least one image to construct a map of the space.

Description

technical field [0001] The present disclosure relates to creating maps using a combination of radar data and optical image data. Background technique [0002] Although vehicle-based mapping is known, current methods suffer from a number of drawbacks including poor angular resolution or imprecise spatial measurements. Contents of the invention [0003] In one embodiment, the present invention provides a method of mapping space using a combination of radar scanning and optical imaging. The method comprises the steps of: providing a surveying vehicle having a radar system and an image acquisition system attached thereto; aligning the field of view of the radar system with the field of view of the image acquisition system; a radar scan; obtaining at least one image of the space using an image acquisition system; and combining the at least one radar scan with the at least one image to construct a map of the space. [0004] In another embodiment, the present invention provides...
